People who are dealing with frequent colds and the flu need to strengthen their immune system, and the Russian scientist Dr. Sergei Bubnovskiy recently uncovered a simple way to do it.

According to the doctor, soaking your legs in ice cold water for 10-15 seconds every day after you get home from work will have a profound impact on the immune system and will prevent colds and the flu in the future.

To perform the treatment, fill a basin with cold water and add some ice – the more you add, the better. The water needs to be ice cold before you soak your feet in it. Keep the feet submerged for only 10-15 seconds and repeat the process every night before going to bed for best results. This method works great on people with weakened immune system – if you’re one of them, you need to perform the method every 4 hours. The method sparked interest in the scientific community, and a recent study conducted at the University of Virginia showed that icy water stimulates norepinephrine production which is an important hormone that will reinforce your immune system.

Besides this, ice cold water can:

Ease sore muscles

Soak the aching muscles in cold water to relieve the pain.

Makes your hair shine

The ice-cold water will make your hair shine as it closes the follicles and makes your hair smooth.

Healthier skin

Cold water therapy will energize your skin by tightening your pores and cuticles and prevent further clotting.

Fights depression

Thanks to the impact on the cold receptors in the skin, ice cold water will improve your mood and reduce the symptoms of depression.
